ISIN', A CORPORATION OF WISCONSIN SWIVEL SUPPORTING MEANS FOR ELECTRICALLYAOPERATED DEVICES Application filed December 30, 1929. Serial No. 417,582.

This invention relates to improvements in :swivel supporting means for electrically operated devices. 4 Y n f This application `is a continuation in part of application for automatic pouring devices, Serial No. 390,058, filed September3rd, 1929.

' Itisone of the objects of this invention to provide an improved swivel supporting means forelectrically-operated devices which has means for cdnducting current from an overhead trolley to the device to be operated, the said means permitting swiveling of the device without interfering with the passage of the electrical current.

A further object of this device is to provide a swivel supporting means for electrically operated devices which is simple in construction, eflicient in operation and well adapted l for the purposes described.

With the above and other objects in view, the invention consists of the improved swivel supporting means for electrically operated devices and all its parts and combinations as set forth in the claims, and all equivalents thereof.

of Fig. 5; and

Fig. 5 is a sectional view taken on line 5 5 of Fig. 3. y

Referring to the drawing, the numeral designates a supporting portion having a central bearing 11 and having supporting arms 12 extending upwardly from each end thereof, each of said arms being forked. A pair of rotatably mounted wheels 13 is carried by each of said arms, and the wheels are adapted to ride along an overhead rail 14. Secured to one end of the supporting member 10 and extending transversely thereof is a bar 15 on which slotted members 16 are slidably mounted. Trolley poles 17 have: their lower ends yieldingly pivoted to the upper portions of the members 16 as at 18, and-have their upper ends forked as at 19 to receive rotatably mounted trolley .wheels 20. The

vsaid trolley wheels each engage trolley wires upper threaded portion 24. Nuts and 26 are threaded on the portionsl 23 and 211, respectively. The enlarged section of the tubular member is also provided with an annular shoulder 27. Positioned between said shoul-` der 2 7 and the nut 25 is an insulating sleeve i28. Rings 29, which surround said sleeve, are formed of a suitable electrical conduct.- ing material. The said rings are spaced apart by insulating rings 30. Loosely posif tioned between the shoulder 27 and the nut 26 is a sleeve 31 having an enlarged upper end portionv 32 formed with anannular groove 33 therein. Balls 34 lare positioned within the groove between the upper end of the sleeve 31 and the nut 26. .The said sleeve 31 is positioned within the bearing portion 11 of the support 10. The enlarged portion 32- of said sleeve rests on the upper end of said bearing 11 and" prevents downward movement of vthe tubular member-,and also provides a swivel connection for the latter.

Secured to and extending fromV the lower portion of the support 10, at'one end thereof.- is a contact block 35 having a plurality of bores 36 therein, within which contact fingers 37 are slidably positioned. The said contact lingers have their inner ends engaging coiled springs 38 in the usual manner, and have their outer ends engaging the ring-shaped contacts 29 which are carried by the tubular member 22. 'f Y The trolley poles 17 are connected by wires 39 with the contact fingers 37. The said lingers, which frictionally engage the rings 29, conduct electricity from the trolley thereto. The enlarged upper portion of the tubuzoo lar member 22 is formed with grooves 40, and within said grooves wires 41 are positioned. The said wires have one end soldered or other- Wise connected to the contact rings, and the other end extending to a starter box 42.

The lower end of the tubular member 22 may be provided with a .hook 43, by means of which any desired electrical device may be supported, the said device being adapted to have wires 44 which extend from the starter box connected thereto to supply the necessary current.

In use of the device any desired electrical mechanism may be suspended from the hook 43. The said mechanism may be an electric ally operated pouring device. By means of the overhead rail and trolley, the device may be moved to thedesired part of the foundry or other building in whichiit is being used, and it may then, by means of the swivel connection within the bearing l1, be rotated -to a desired angular position. Due to the novel combination of the rotary contact with an overhead supporting means, this swiveling operation may be performed without in the least interfering with the conducting of electricity from the overhead trolley to the machine.

, Although only one form of the invention has been shown and described, itis not desired to be limited to this exact showing, as the broad concept of the invention includes all changes and modifications as may. fairly come within the scope of the claims. What I claim is:

1. A supporting means for electrically operated devices, comprising an overhead track, -a movable frame member having electrical conducting means in connection therewith and entirely suspended from said track, a supporting member for an electrically oper ated device pivotally suspended from said frame member, electrical conducting mea-ns in connection with said supporting member, and means for conveying electricity from the conducting means of said frame member to the conducting means of said supporting member, without interfering with the pivotal movement of thelatter on the frame.

2. A supporting means for electrically operated devices, comprising an overhead rail, a frame movable along said rail and entirely suspended therefrom, a supporting. member for an electrically operated device pivotally suspended fromsaid frame, trolley Wires extending parallel to said rail for conducting electricity from an outside source, trolley poles in connection with said frame member engaging said trolley wires, contact rings carried by the supporting member, and brush members carried by the frame and in connection with the trolley poles, said brush members frictionally engaging the contact rings on the supporting member to conduct electricity thereto without interfering with pivotal movement of the supporting member on the frame.

3. A supporting means for electrically operated devices, comprising an overhead rail, a frame movably suspended from said rail, a bearing mounted in said frame, a supportingmember for an electrically operated device revolubly mounted in said bearing, a suspending member carried by a lower portion of said supporting member, a trolley wire extending parallel to said rail for conducting electricity from an outside source, a trolley pole carried by said frame and engaging said trolley wire, Contact rings surrounding said supporting member, and brush members carried by the frame and electrically connected with said trolley pole, said brush members frictionally engaging the contact rings on the supporting member to conduct electricity thereto without interfering with pivotal movement of the supporting member with respect to the frame.

In testimony whereof, I atix my signature.
